Complete planning and scheduling of all spacecraft operations is a challenging area with the remote agent experiment at Deep Space 1 being a pioneering system. Still the complete approach is rare in practice. For example, in the Mars Express (MEX) mission, planning and scheduling techniques are used to solve some subproblems namely scheduling command upload and data download. In this paper we d...

Aircraft maintenance planning and scheduling constitute planning, control and execution of materials (spare parts), operations (inspection, disassembly and assembly activities) and resources (labour, machines, transport equipment, etc.). This is a complex problem due to large number of components involved at various planning and execution levels, and the size/nature of resource-intensive mainte...

Classical control systems utilize implicit analytical models and select inputs using numerical computation in order to achieve desired plant performance in real time. Artificial intelligence planning systems utilize explicit symbolic or logical models of discrete operations and construct consistent planned sequences using symbolic reasoning to achieve specified task goals. In the development of...

Currently, the planning of the biomass collection operations is performed relying on the contractor’s experience without the use of any dedicated planning tool. It is expected that more explicitly formulated planning tools would provide benefits on securing the supply chain of biomass feedstock. In this study, the problem of finding a permutation schedule for a number of geographically disperse...

Due to the lack of systematic reliability analysis, intuitive decisions can usually be made in planning process operations under uncertainty. We propose a new analysis and optimization framework to address this problem. By using the technique of probabilistic programming, the solution provides comprehensive information on profit as a function of the confidence level as well as its sensitivities...

Process planning is an essential component of computer aided process planning (CAPP), which involves operations selection from design features and operations sequencing of these selected operations. It makes process planning a complex combinatorial optimization problem to conduct of these two steps simultaneously. In this paper, we propose a cooperative simulated annealing (CoSA) approach for t...

This is the second part of a two-part survey investigating transportation network postdisaster planning and management. The first part focused on efforts and models for the estimation and assessment of post-disaster network performance (PDNP). This paper addresses the problem of decision-making and planning of post-disaster network operations (Post-Disaster Network Operations Planning – PDNOP)....
